This invention relates to a means-for controlling the tension in the material being wound in accordance with the diameter of the wound mass without physically contacting the material.

An object of the invention is to provide a control dependent upon the sizeof the wound package which will regulate the speed ratio between the linear speed of the material being wound up and the linear speed of the material as it is being fed to the winding means, and thus control the tension in the material.

A further object of the invention is to provide an indicator which will indicate that the package has acquired a predetermined size and that the feed should be shifted to the next package without having any elements in physical contactwith.

the material.

Another object of the invention is the method of producing wound packages of artificial silk in which the-tension in the material is to improve its dyeing properties, maintained uniform, or decreased to produce a fluffy package to improve its washing properties by controlling the feeding and taking up of the material, the

control being in accordance with the changing diameter of the material on the package. More specifically the invention is applied to an artificial silk spinning machine in which the. spinning, solution is fed by a motor-driven pump through a coagulating solution, formed into a thread and wound upon a bobbin. The bobbin is rotated at a constant axial -speed and as the package is wound up the linear speed of the maincreased 2,214,332, dated September 10, 19, 142,580, May 14, 1937. Application during operation of the machine.

terial being wound constantly increases due to the increase in diameter of-the package. The feeding means must beoperated at a variable speed to compensate for this change in linear speed. If a package with uniform tension is desired, the speed of the pump will be increased to exactly compensate 'for the change in linear speed of the take-up. If a package with increasing tension is desired so as to obtain better dyeing properties, the speed oi-the pump will be varied so that the change in feed will not quite'compensate for the increase in the linear speed at the take-up and will thus rial being fed at a greater rate than the change of linear speed at the takeup and ,thus decrease the tension'in the material.

The plior practices element contact the material and thus control impose a gradually'increastension on the material. If. a package withdecreased tension is desired, the .pump will be, operated to change the linear speed of the matefor controlling the tension" inthe material have been to have an the feed ortaken along line ll of P18. 4.

Fig.7isa ,v tion of Fig. 5' when adapted for winding material from one holderor supp y source to anto have gearing interposed between the take-up and the feeding means which changes the speed ratio between the two in a predetermined cycle The first method is objectionable in that it applies an undesirable rubbing action on the filaments which tends to injure them. The second method is objectionable in that should the material cease feeding the speed ratio would continue to change in its cycle and the ratio between the two would be improper when the winding is resumed. According to the present invention, however, a light-sensitive cell is placed adjacent the winding package and a insuch a manner that as the package increases in diameter it intercepts the rays from the light source. This causes the current in'the lightsensitive cell to decrease in accordance with the amount of light blocked ofl. The cell is connected in the control circuit for the feeding device or pump so as to vary its speed in accordance with the current in the cell.

From the above it will be apparent that the speed of the feed device will be controlled in accordance with the diameter of the wound s'quently the linear speed of take-up.

' ends of the bobbins to prevent axial of the bobbin.

an artificial silk spinning machine. The particu-' lar spinning apparatus shown in the drawings and described in this specification is of the type adapted to produce rayon by the viscose process. However, it should be borne in mind that the spinning apparatus is shown for purposes of i1- lustration only and that the invention may be applied to other types of spinning or other machin... in which it is desired to wind material and control the tension in the material in accordance with the diameter of the wound package without physically contacting the material. Without going into details, of construction of the spinning apparatus shown in the drawings, it comprises in general a framework I upon which is supported a tank 2 containing a coagulating or precipitating bath 3 of suitable well-known composition. A gear pump 4 forces viscose solution through a pipe 5 to a filtering device Ii from which it passes through a goose-neck I to a spinneret 8 beneath the surface of the bath 3. The pump 4 is driven by a motor 9 through chain III and suitable gearing II. All of this structure is mounted on frame I midway between bobbins I1, I10. as is shown by the position of the filter devicet in Fig. 4 and is duplicated throughout the length of the machine for each pair of bobbins. A door I2 is hinged at I3 and extends along the machine and encloses the gearing and other mechanism.

The filament-like jets of viscose which issue from the spinneret 8 are coagulated by the precipitating bath 3 and are gathered into a thread that passes through guide I5 on a longitudinally movable traverse bar It to bobbin I1 or Ila, as

will be later described, and wound into a package. The traverse bar is mounted in brackets I8 on rollers I9, I9 and is reciprocated in a manner to be later described.' 7 I The bobbins I! and Ila are supported at each end by a pair of rollers mounted on shafts and the guide will then traverse the thread along bobbin IIa.

The controlling mechanism for the machine 2 comprises a light-sensitive cell 40 mounted on a bracket 4|. The light-sensitive cell may be of any suitable type capable of changing the current in the cell in accordance with its illumination. Bracket 4|- is carried by a bar 42 ex-- tending along the machine. Secured to bracket U is a light source 43 with its beam focused on the light-sensitive cell. As shown in Figs. 1, 4, and 5, an attachment is provided for each bobbin and is positioned adjacent the bobbin-in such a manner that the package as it increases in size will intercept the rays of light from the lightsource. This decreases the illumination of the light-sensitivecell and thus decreases the current in the cell. The cell is connected by wires 45, 48 through contact 41 of switch'S, to be later described, to an amplifier 48 which amplifies the current in the cell. The amplifier is connected to a controller box 49 which contains solenoid or other current responsive device 50 which acts against spring 5| to move the arm 52 (pivoted at 53) in proportion to the current in'the lightsensitive cell to control rheostat 54 in the field 55 of pump motor to regulate the speed at. which 2] which are driven by gears 22 from motor 23. i

As shown in Fig. 4, the rollers are mounted on shafts 2i and have flanges 24 which contact the movement The means for reciprocating the traverse bar I6 is driven'by the motor 23 through gear 28v mounted on motor shaft 25.

Gear 26 engages gears 21 and 28 which operate the cam 29 in the manner fully described in U. s. Patent 109,708

to oscillate the member 30 about its pivot 3!. The member 30 has a bifurcated end 32 which-engages pin 33 on a handle 34 which is pivoted to the traverse bar I6 at 35.

It will be noted in Fig. 4 that while both bob-- bins are rotating, only one of the pairof bobbins is'being used for winding. When that bobbin is filled the traverse bar is shifted so that the guide I5 on" the bar leads the thread, to the reserve bobbin. In this manner the winding may be to change bobbins. Themanner of changing or shifting the thread from one bobbin to the other will now be explained.

. when it is-desired to shift the traverse frombobbin I! to Ila, the operator removes the springpressed locking pin 31 from an aperture similar to'fld in the traverselbar I6 and pivots handle about pivot 35and removes pin 33 from the 32 and the locking pin 31 engages'aperhire 33a;

the-thread is fed to the bobbin.

Motor 23, in this embodiment of the invention, is a constant speed motor. Bobbins I1 and I'Ia are therefore driven at a ,constant axial speed.

The thread will be taken up by the bobbins at a constantly increasing linear speed as the diameter of the bobbins increase. The feed means must therefore be adjusted to compensate for this increase in linear speed so as to maintain the desired tension. in the material. This is done by selecting aproper resistance 55 in the field of the feed motor and varying it to accurately control the speed of the same. If desired the feed may be adjusted to gradually increase the tension in the material so as to produce a package which has better dyeing properties, may

be adjusted to maintaina uniform tension in the material, or may be adjusted to gradually decrease the tension in the material so as to produce a'fiufiy package more suitable for washing. Further it is pointed out that the controlling mechanism does not include any element which contacts the package to determine its size and which would, if used, cause undue rubbing on the material .which is fragile and very easily broken.

' continued without having to stop the machine As shown in Fig. 4 "each bobbin has a control unit mounted adjacent thereto. These-units'are shownin detail in Figs. 2 and 3. It will be noted that the cell faces downward and is shielded from the usual overhead lights used in the building.

the amplifier when the feed is changed to that bobbin by the shifting ofthe traverse bar.

Switch S also has a contact to connect contacts 56 and 55a in the signal circuit for the bobbins I1 and Ila. This signal is operated by a contact- 51 on'arm 52'which bridges contacts 58, 58, when the arm has moved into the position it occupies when a full package has been, attained and closes the circuit from battery J3 tolamp 60 and 60a and an audible alarm as'at 6|. to the operator that the package be seen thereindicates has acquired its full sizeand that the traverse should be shifted tothe next Itwill source to the bobbin or other receiving roll tially fore that the control unit and signal unit for each bobbin is put into operation automatically when the traverse is shifted.

In the above description .the speed of the feeding means has been varied while the speed or the take-up has been maintained constant. I The same results obviously can be obtained by feeding the material at a constant speed and taking it up at a variable speed.- This would involve only the shifting of the control rheostat from the field circuit of the pump motor to the field circuit of the take-up motor.

Also the shifting of the one bobbin to another may be done automatically and the circuit made to give the signal could initiate the mechanism for making the change over. The signal circuit may also operate a stopping mechanism when the package hasacquired its proper size.

.Also if desired a godet wheel may be geared to traverse or feed from the pump or feed motor to assist in feeding the,

filaments to the take-up means and have its speed varied with variations in the speed of the pump or feed motor.

The modification in Fig. 6 shows the control being split between the winding or take-up motor and the feeding motor. In this modification arm 52' is actuated by the solenoid as in the former disclosure. It moves member BBmounted to slide in bearings 7 slot connection. Member 68 carries contacts 63 and 64 which bridge contacts 62, 54 and 6 5, 66 as shown. Contacts 54' and 65 are connected in the fields 55' and 61 of motors! and 23' and are formed as shown in Fig. 6 with one half of their length as a variable resistance. They are arranged so that during one half of the movement of member 68 the resistance in the field of one motor will vary and during the second half oi themovement of member 68 the resistance in the field of the other motor will vary. This will result in the speed of the first motor being varied during the first half of the winding operation and then running'at a constant speed; and

the second motor running at a constant speed during the first half of the winding operation and at a variable speed during the second half.

The modification of the invention illustrated in Fig. 7 is the same as that illustrated in Fig. with the exception that the motor 9 is suitably connected to drive a supply roll I2 bearing elongate material which is wound upon the bobbin or other receiving roll l1. As the effective diameter of the bobbin or other receiving roll H increases so as to increase the peripheral speed of the receiving roll, the peripheral speed of the supply roll 12 is progressively increasedso as to maintain the. material being wound under substantially no tension or under a uniform tension.

The modification illustrated in Fi 8 is the same as that illustrated in Fig. 5, except that the'motor 9 is suitably connected with a roll Il so as to drive the same and to supply elongate material from a suitable supply roll or other H. As the bobbin or other receiving-roll ll'increases in diameter, the peripheral speed of the roll II will be increased so as to maintain the elon a ma ri l being wound under substannotension or under a constant tension.

Wire drawing. enameling, film windingand various textile machines are examples where this type of control would be desired. As many apparently widely different embodiments of this invention may be made without departing from the spirit and scope thereof, it is to be understood that it is not to be limited tothe specific embodiments described except as defined in the appended claims.
